I have now had this happen exactly the same on two different days
Using scrotwm, latest -current running dual head
Running at same time: thunderbird, firefox, xterm
Upon writing a file in kate, immediate fail back to console.
File was successfully written this time, corrupted last time.
$ dmesg

A human being should be able to change a diaper, plan an invasion,
butcher a hog, conn a ship, design a building, write a sonnet, balance
accounts, build a wall, set a bone, comfort the dying, take orders,
give orders, cooperate, act alone, solve equations, analyze a new
problem, pitch manure, program a computer, cook a tasty meal, fight
efficiently, die gallantly. Specialization is for insects.
